• Example B1 Action against Puccinia graminis on wheat
• Wheat plants were sprayed 6 days after sowing with a spray mixture (0.002% active ingredient) prepared from wettable powder of the active ingredient. After 24 hours, the treated plants were infected with an uredospore suspension of the fungus. After incubation for 48 hours at 95-100% relative humidity and approx. 20 ° C, the infected plants were placed in a greenhouse at approx. 22 ° C. Red pustule development was assessed 12 days after infection.
• a spray mixture 0.002% active ingredient
• a spray liquor prepared from wettable powder of the active ingredient was poured into wheat plants 5 days after sowing (0.006% of active ingredient based on the volume of the soil). After 48 hours, the treated plants were infected with an ureidospore suspension of the fungus. After incubation for 48 hours at 95-100% relative humidity and approx. 20 ° C, the infected plants were placed in a greenhouse at approx. 22 ° C.

• a spray mixture prepared from wettable powder of the active ingredient was poured into barley plants about 8 cm high (0.002% of active substance based on the volume of the earth). Care was taken to ensure that the spray mixture did not come into contact with the parts of the plants above ground. After 48 hours, the treated plants were dusted with conidia of the fungus. The infected barley plants were placed in a greenhouse at approx. 22 ° C. and the fungal attack was assessed after 10 days.
